Abstract
The invention relates to a seat tube connecting structure, which belongs to the technical field of a bicycle stand. The seat tube connecting structure comprises a fastening ring, a fastening bolt and a tube-shaped holding part. The seat tube connecting structure is an independent part assembly which is applied at a combination position of a seat tube of a bicycle faldstool and a bicycle stand; though the structure is simple, the combination problem of the seat tube of the bicycle faldstool and the bicycle stand in the prior art can be solved, and the problems that the force is concentrative and the combination strength is bad are effectively avoided.
Description
Technical field
The present invention relates to a kind of pipe connecting structure, belong to the bicycle rack technical field.
Background technology
At present, existing bike saddle pipe connecting structure is as shown in Figure 1, and it is to be made up of vehicle frame 30 and 40 of cushion groups; Vehicle frame 30 is provided with joint portion 31; Joint portion 31 is provided with profile groove 310, and joint portion 31 combines to be provided with bunching piece 32, and bunching piece 32 closes packing with locking part 320 bundles; Cushion group 30 is provided with a pipe portion 41; This pipe portion 41 is arranged at vehicle frame 30 set joint portions 31; Through bunching piece 32 is closed packing with locking part 320 bundles, make in profile groove 310 gaps of being located at joint portion 31 and contract, and make the joint portion 31 of vehicle frame 30 tighten a pipe portion 41.But there be stressed concentrating in this structure; The problem of poor bonding strength: when its bunching piece closes packing with the locking part bundle; The inside crumple in all both sides in the joint portion of vehicle frame is tightened the joint portion and is arranged at the seat pipe portion in it, and its application of force of tightening concentrates on an and arranged on left and right sides of pipe portion periphery; Stressed concentrating makes the forward and backward both sides of seat pipe periphery be prone to produce fracture.
Summary of the invention
The objective of the invention is provides a kind of pipe connecting structure for solving the problems of the technologies described above.
Above-mentioned technical purpose of the present invention is achieved through following technical scheme:
A kind of pipe connecting structure comprises tight loop and locking bolt, and it comprises that also a tubulose grips seat.
A said seat pipe that is used for fixing the bicycle bench that grips.Through the present invention; Cause the seat pipe and vehicle frame indirect securement of bicycle bench; Efficiently solve in the prior art the stressed concentrated problem that the gravity because of human body causes the joint portion of cycle frame, also solved the problem of seat pipe jointing intensity difference of joint portion and the bench of vehicle frame in the prior art.
Preferred as technique scheme, said to grip seat be a blind-hole type tubular structure.
Preferred as technique scheme, the said body that grips seat is provided with the blocking flange.This blocking flange not only has spacing effect, makes that also the intensity that grips seat self is higher, and stability is higher.The force analysis result shows, receives force intensity higher here.
Preferred as technique scheme offers profile groove on the edge mouth of the entrance of the said body that grips seat.
Preferred as technique scheme offers the preshrunk gap that connects the pedestal total length on the said tube body wall that grips seat.
Preferred as technique scheme, the said body that grips seat is provided with some fastening lines.
The setting of fastening line makes the seat that grips of the present invention to be fixed firmly by the effect of the middle pipe of bicycle through tight loop and locking screw.
Preferred as technique scheme, said tight loop has two locking holes, is carved with the screw thread that matches with said locking bolt at least one hole.This screw thread is different from the screw thread between the plain bolt and plain nut in the prior art, and this screw thread broad and darker can effectively avoid being threaded of prior art loosening because the reason of bicycle concussion produces.The width of thread of prior art is generally 0.3～0.6mm, the degree of depth 0.3～0.6mm; And here, locking hole is 2～3mm with the width of thread of locking bolt, the degree of depth 2～3mm.
In sum, the present invention has following beneficial effect:
The present invention applies to one of the junction of the seat pipe of bicycle bench and vehicle frame independently part group; Although it is simple in structure; But can solve the problem that combines of seat pipe with the vehicle frame of bench in the prior art, effectively avoid stressed and concentrated the problem of poor bonding strength.

The specific embodiment
Below in conjunction with accompanying drawing the present invention is done further explain.
This specific embodiment only is to explanation of the present invention; It is not a limitation of the present invention; Those skilled in the art can make the modification that does not have creative contribution to present embodiment as required after reading this specification sheets, but as long as in claim scope of the present invention, all receive the protection of patent law.
A kind of pipe connecting structure, as shown in Figure 2, it comprise tight loop 1 ', the locking bolt 2 ' and grip the seat 3 '.Gripping seat 3 ' be a kind of tubular structure, and is the tubular structure of blind-hole type, its body be provided with blocking flange 31 ', offer on the tube body wall preshrunk gap 33 that connects self total length '; Also offer on the body fastening line 34 ', offer on the edge mouth of the entrance of body profile groove 32 '.
The present invention is an independently part group, and is as shown in Figure 3, it grip the seat 3 ' be used to peg graft and the fixing seat pipe of bench; And seat 3 ' peg graft the middle pipe of bicycle that grips of the present invention, again through a tight loop 1 of the present invention ' grip 3 ' closely be connected with middle pipe with locking bolt 2 ' make.
